Coffee Grounds/Walnut Shells for Ballast

[carpediem4570]

Greetings All:

I drink a lot of coffee.  Grind my beans.  Consequently, I have a lot of coffee grounds.

One day, I dried out the grounds and put them in a glass jar with the idea of using it for track ballast.  Has anyone ever tried this?

Oh man; I just had another idea.  Coal load for the tender.  What say you?

I look forward to your responses.

 Kind regards,
Max

Wow, so many views and no comments…

I did some research and it says make sure your coffee grounds are dry, otherwise they will go moldy.

Something else that was suggested was ground walnut shells.  I have several five gallon pails full of ground walnut shells.  And of course, if you need a finer grind, throw them in a coffee grinder.  Anyone use walnut shells?

Kind regards,
Max

Well, this is a forum for the RailPro products, not a general discussion on scenery...

usually close to neutral in PH, so no corrosive effect.

being organic, I'd worry about it eventually decomposing.

Here's a discussion on them:;
